Answer:
C
Step-by-step explanation:
Both lines start and end on x = 3
The lower line has a positive slope and a y- intercept of - 2
The lower line has an open circle at it's endpoint indicating it cannot equal 3
x - 2 for x < 3
The upper line has a positive slope and a y- intercept of - 1, if we project the line. The line has a closed circle at it's start indicating it can equal 3, thus
x - 1 for x ≥ 3
Hence
x - 1 if x ≥ 3
x - 2 if x < 3 → C
Answer:
When I solve it , I got the answer not the same with you.
( i ) The lateral area of the prism is 204.
( ii ) The total surface area of the prism is 744.
Step-by-step explanation:
( i ) We got that answer because we multiply 17 cm with 12 cm.
( 17 x 12 )
Because it ask only ask for the lateral area which is length and width.
Lateral means side or side so it is length and width not height and
width/length.
( ii ) We got that answer because first step we multiply 17 cm with 12 cm.
We also have to multiply the gotten answer with 2.
Second step, we multiply 12 cm with 7 cm. Almost gonna forgot,
we also have to multiply the gotten answer with 4. Then, add the first
step and second step to make the total surface area.
= ( 17 x 12 x 2 ) + ( 12 x 7 x 4 )
= ( 204 x 2 ) + ( 84 x 4 )
= 408 + 336
= 744

Answer:
(sin^2 w + 1) / cos w.
Step-by-step explanation:
Note: sec w = 1 / cos w and csc w = 1/ sin w.
So we have:
(sec w(1 + csc^2 w)) / (csc^2 w)
= 1/cos w ( 1 + 1/ sin^2 w) / (1 / sin^2 w)
= ( 1/ cos w + 1 / sin^2 w cos w) * sin^2 w
= sin^2 w/ cos w + sin^2 w / (sin^2 w cos w)
= sin^2 w / cos w + 1 / cos w
= (sin^2 w + 1) / cos w.
When you expand the binomial, you isolate each of the parts.
So, (x-y)^4 would turn into...
x^4 - y^4
The powers stay the same because (outside the parenthesis) you multiply them with whatever is inside the parenthesis. In this case, would be 1. All variables and numbers without a listed power have a power of one. Multiply 4*1 to get 4.
